S.D. Codified Laws § 17-2-1
All legal and other official notices must be published in a legal newspaper as described in this chapter. When any legal notice is required by law to be published in any newspaper, the newspaper publishing the notice shall place the notice on a statewide website, established and maintained as a repository for such notices by an organization representing a majority of South Dakota newspapers.
The newspaper shall include a prominent link to the statewide website on the newspaper's website homepage or post all public notices to the newspaper's website in a manner that is accessible and free to the public, if the newspaper maintains a website. The affidavit of publication must state that the newspaper is a legal newspaper. The affidavit is prima facie evidence of that fact. Each affidavit of publication must state in plain terms the fees charged.
